swollen knuckles

Recently my girlfriends (RIGHT, CENTER, MIDDLE FINGER) knuckle and her (LEFT,LAST, MIDDLE FINGER ) knuckle have become very red and swollen. She describes it as being " swollen, red, very painfull, looks like broken bloodvessels, and itchy (mostly itchy in the morning). I've searched websites for awhile and hav'nt been able to come up w/anything . Is there anyone out there who might now what the problem is?
